Many many moons ago I used a plugin that created a grid on a photo. You could click and drag the points at the intersecting lines to distort the photo. This is sort of like the new 'liquify' function but you have complete control over the control points. Liquify is a drunken approach to what I am looking for.
The plugin in the link above was only tested up to Photoshop 4. Has anyone used this with PS6+? Does anyone know of another plugin that is similar and compatible with PS6 and 7?
